i use coconut fibre bedding and that SAME EXACT thing happened to my BP today. At first I was worried that maybe he was trying to regurgitate his meal, but I quickly realized that he has some substrate in his mouth. Needless to say from now on I will most likely use tongs instead of letting him hunt down the mouse. The weird part is that my BP didn't even go to his water dish to try to clear out his mouth or anything. He just layed there with his head up and looked almost like he was yawning repeatedly. I have heard from maybe people that ingesting some coconut fibre shouldnt hurt your snake though.![]()
